SPEIFICATION forming part of Letters Patent No. 347,307, dated August10, 1886.

Application filed June 14, 18r6. Serial No. 205,14l.

To all whom it may concern: i

Be it known that l, SAMUEL P. SWARTZ, of Allentown, in the county ofLehigh and State of Pennsylvania, have invented certain new and usefulImprovements in Soldering-Irons; and I do hereby declare the followingto be a full, clear, a-nd exact description Aof the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawing, which forms.-part of this specification.

4 be more fully described hereinafter.

'Ille'object of my invention is to l'orm upon the soldering-point aprojection which will lit in asutable socket in the metallic portion ot'the handle, and thus enable the point to retain its heat, and to fastenthe point to the handle by an intermediate metallic rod, which connectsall of the parts together.

The accompanying` drawing represents a vertical section ot' asoldering-iron which embodies my invention.

A represents a solderingpoint, which has a suitahlyshaped projection, B,formed upon its inner end, and which projection fits in acorrespondingly shaped socket, C, which is made in the inner end'of thehollow metallic shank D. The inner end of this metallic shank D is ofthe same diameter as the solderingpoint,and bears directly against theshoulder which is formed on the point, so as to form an intimate Contactbetween the two parts. The two part-s being thus brought in contact (Nomodel.)

*L both by the tenon and socket and the ends or shoulders, becomethoroughly heated, and the metallic shank D, instead of robbing thepoint ot' its heat, helps it to retain it. Through the projection ortenon B is formed a suitable opening, in which the hooked end of the rodF is made to catch. This rod F is screw-threaded at its outer end, andis made to pass through the metallic portion D ot the handle and intothe handle G, which is provided with a nut, H, at its outer end. rIheouter metallic shank, D, is also made screw-threaded at its outer end,and is' provided with a shoulder, l,which acts kas a stop for the woodenhandle.- The wooden handle being passed over the outer ends of themetallic rod and the shank D, screws upon the shank D, while themetallic rod enters the nut H, and thus the handle is tenou, the nutwhich 'screws upon the outer end ofthe rod, the hollow metallic shank D,provided with a socket to receive the tcnon, and the handle G,substantially as shown and described.

r In testimony whereof I affix my signature in presence of twowitnesses.
